Abstract

A railroad switch machine includes a pair of switch blades, an electric motor mechanically coupled to the pair of switch blades, a pair of input terminals connected to a DC power supply for receiving a power signal and a regulator to adapt the power signal between the input terminals into a motor current applied to the electric motor. The regulator includes a plurality of switches connected between the pair of input terminals and two phases of the electric motor. The switches are transistors and the regulator also includes a controller adapted to drive each transistor with a respective command signal to adjust a value and a direction of an intensity of the motor current.
